I v saidibottomflange (Z, are I foi'med 'tangentiali oil holeswlpreferably W four*in number, Y arranged? equidistant around theysleeve-' and slanting slightly downward and in the direction in whichthe shaft revolves,toadapt the oil to bedrawn id or sucked in by therotation ofthe-shaft, while upwardly inclined grooves Z on the innersurface of the Zbearing sleeve, and i wh ch start from the inner endsofthe tana 'glltlullOll holes and extend only a short distance, directthe veil entering through she ve, thereby effectually automaticallyoilmg thebearing the full lcngt'hmf the, sleeve.

The shaft isthus autor'i aticallyf oiled by rotation; of the gearing,and the usual oil grooves which haveheietoi ore been made to run thewhole lengthof the bearlng are eliminated, thus greatly increasing thedurahilityof the machine. In the fort shown,

the, upper flange onthe sleeveaD restsupon loo a, tubular projectionextending ,up into the howlat the upper end of the housing within whichtheiseparato-r bowl rotates, 'andbetween' the top and intermediateflanges is placed; an elliptical spring E, or spring of The casing orhousing'A may be of" elliptical form hear ng on the interior wallof saidprojection and the exterior of said sleeve and serving to'feenter theshaft while allowing it to yield sngntly of centrifugal force. A

It will beunderstood, of course, that the form of the flange on whichthe oil is splashed may be varied, and although it is preferablyintegral with the bearing sleeve, it may be formed separately andrigidly secured thereto; and instead of four equiunder the actiondistant tangentially inclined oil holes in the hearing sleeve a greateror less number may be employed, and in some cases the upwardly inclinedgrooves from the inner ends of omitted, but they are preferable anddesirable for greater efficiency and durability of the bearing with moresatisfactory results. 1 Having thus described my invention,'what I claimas new and desire to secure by Letters Patent of the United States is:

the oil holes may be 1. A vertical shaft bearing comprising a sleevehaving an exterior thereon and oil holes therein extending tangentiallyto and in the direction of rotation of the shaft and terminating inupwardly inclined ducts, whereby oil thrown onto said flange will bedrawn into the sleeve and carried upwardly along the shaft.

annular flange 2. A vertical shaft bearing including a sleeve havmg anexterior annular flange gential oil holes or ducts leading said chain)er,

a bearing sleeve on said shaft having an annular fian e thereon andadjacent tanthrough which the oil thrown or splashed upon said flange bythe rotation of the gear-wheel is drawn into the sleeve and forcedupwardly along the shaft.-

4. In combination, a housing having an oil chamber, a gear-wheel havingits periphery partly immersed in oil in said chan'iher, a verticallydisposed shaft having a gear thereon in mesh with said gear-wheel, and abearing sleeve on said shaft having a circumferential flangeandtangential oil holes adjacent said flange and upwardly inclinedgrooves leading from said holes, wl'iereby oil splashed on said flangeis drawn into said sleeve by the rotation of the gear-wheel and carriedupwardly along the shaft.

5. Incombination, a gear casing having an oil chamber in its bottom, agear-wheel having its periphery partly immersed in oil in said chamber,a vertical shaft having a gear thereon in mesh with said gearwheel; saidshaft being journaled in upper and lower bearings; said upper hearingcomprising a sleeve surrounding the shaft and having an annular flangethereon adapted to catch oil splashed by said gear-wheel, and saidsleeve having oil holes thcrethrough adjacent saidflange and grooves onthe in nor surface thereof slanting upwardly from the inner ends of said011 holes so as to conduct the oil entering said holes upwardly alongthe shaft.

In testimony whereof I afiia my signature in the presence of twowitnesses.
